Sir Clive Alderton, the principal private secretary and top aide to King Charles, will step down next year after two decades in the Royal Household, marking a major leadership transition.

Buckingham Palace praised his tireless support and counsel, noting his role in ensuring a smooth transition to his successor and continuity for the King.

In a staff message, Alderton said it has been an honor to serve during historic times and that he will continue to support in a less formal capacity for life.

recruitment for Alderton’s successor is expected to begin before spring or summer 2027, with the appointee joining RAVEC, the Royal and VIP Executive Committee.

Alderton has been involved in royal governance, influencing decisions such as the Coronation Committee and advising during international engagements as the new reign begins.

He was knighted in 2022 under the Royal Victorian Order for services to the sovereign and the royal family.

Ahead of his departure, he will focus on the royal household’s work and aid the selection, onboarding, and transition of his successor.

Alderton sits on RAVEC, and his replacement will also join the committee overseeing official protective security.

Prince Harry reportedly nicknamed him “the Wasp” and regarded him as one of the “men in grey suits” at the Palace, reflecting influence within the Royal Household.

Harry’s Spare depicted Alderton as part of a trio of top aides, though insiders dispute that this trio blocked reconciliation with the King.

The leadership change underscores a focus on continuity for the King and Queen as the Royal Household transitions.

Harry’s memoir Spare, published in 2023, described Alderton as “the Wasp,” a nickname used for several staffers to signal charm with a sharp, energetic presence.
